      The PHP_STREAM_IS_XXX "constants" are actually defined as pointers to the underlying
      stream operations structure.  If your extension (or some other extension) defines additional
      streams, it should also declare a PHP_STREAM_IS_XXX constant in it's header file that you
      can use as the basis of this comparison.

      This function is implemented as a simple (and fast) pointer comparison, and does not change
      the stream state in any way.
